Bayer Leverkusen sporting director Rudi Voller admits they could lose Kai Havertz this summer.
“I am glad that we still held [on to Kai Havertz] this year," Voller admitted on 100% Bundesliga.
“We'll see how it looks in summer. He still has a contract until 2022 - these are, of course, the classic facts.'
“There was already interest in the summer, but we told him that it would be good for him to stay with us for another year. And that was the right decision."
